To all whom it may concern Be it known that I, WILLIAM P. MCLAUGH- LIN, a citizenof the United States, residing in borough of Brooklyn, city of New York. in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

The invention relates to an improved tabulating mechanism for typewriting machine's.

The object of the invention is to combine in a single machine a decimal tabulating mechanism and a column skipping mechanism, both 0 erable from a single set of keys, so that, by't e operation of one key, the carriage may be released, and caused not only to be arrested at any desired decimal position in the column to which the carriage is skipped.

The invention comprises as a feature there of an adjustable carriage stopping mechanism for each column, each of these stopping mechanisms being adjustable by one column key to arrest the carriage at any desired decimal position of the each of these mechanisms being ineffective to arrest the carriage at all unless the proper column key is operated.

In the embodiment of the invention hereinafter specifically described, the adjustable carriage stopping mechanisms for the sev-- eral columns are shown as groups of stops, preferably vertical sliding rods, the number of stops in each group being equal to the number of decimal positions in the column; and the adjustment consisting in selecting, by means of the column key, the desired stop of each group so that thereafter, by another or further movement of the key, the selected to arrest the carriage at the column represente by it.

In the preferred form re arrapged in a row the rows being par llel to leach other and to the line of movefnnt of the carriage. The column key levers are prbgressively lengthened so that each may reach the row of stops controlled by it; and, i order that each lever may cooperate with any stop in its row or group,'the levers are ounted not selected column, and

of the invention,-

only to have a downward movement for projecting the stops, but also to have a lateral .swmgor stop selecting movement.

The manner in which the keys are mounted; the means for assuring the proper stop selecting movement of the same, and the means for returning the keys to a normal setting are more or less important features of the.invention.- The invention in the form shown also comprises a series of racks, one for each group of stops all carried by the carriage; and, adapted to be set in any desired column position on each rack, is a column stop or plug for cooperation with the key selected stop of the group corresponding to that rack.

It is a feature of the invention that the mechanism may tabulator, with the column skipping feature eliminated; and that in this use of the invention, any one of the column keys may be used repeatedly to move the carriage rom one column to the next, the decimal stopping position in each column being determined as before by the key adjustment or stop selecting operation, before the key is depressed.

Other features of the invention will hereinafter appear.

In the accompanying drawings, Figure 1 is a perspective view of the assembled parts as applied to an Underwood typewriter. Fig. 2 is a side view of the mechanism looking from the right of the machine, the parts being in normal or inactive position. Fig. 3 is a view similar to Fig. 2 except that the parts are in the position assumed when one of the column keys is depressed. Fig. 1 is a top plan view of the lever system showing the normal relation of the same to the stops. Fig. 5 is a detail view illustrating the manner of mounting the keys.

The invention is shown as .applied to an Underwood typewriter. The carriage 1 is driven in letter feed direction from the usual spring drum 2 by the strap 3. The letter feed movement is controlled by an escapement wheel 4, which carries a pinion 5 meshing with a rack 6, the latter being supported from the carriage, at each end of the same, by means of an arm 7. The escapement wheel 4 is controlled in the usual manner by an escapement device 8 operated from the type keys. To permit the carriage to be thrown independently of the escapement mechanism, provision is made for disengaging the escapement rack from the pinion 5'- with which it normally meshes; and to this end, the-arms 7 by which the rack'is carried are pivoted to the carriage as at 9, one of the arms being extended to carry the release key 10; Depression of the key 10 causes the rack to be lifted out of engagement .with the escapement pinion 5, thus releasing the carriage. The rack 6 when in normal position rests and moves u ona roller' 11 which number, each representing a column posithe keys 12,- the following l tion, but may be of any number des red. The keys 12 are carried by levers 13 pivoted between frame members Hand 15 and having arms 16 which extend to the rear of the pivots. For releasing the carriage from means is provided. Crossing each of -t bar 17 which is integral withandis supported from two vertical arms 18.-' The arms 18 are pivotally'attached to arms 19 which are made integral by a cross bar 20 and are connected to a sleeve 21,-which is fast to a rock shaft 22 mounted in'brackets Also fast'to the rock shaft .22 is a lever arm 23, connected by a link 24: with a lever 25 pivoted at 26 to ,the frame. The

, forward arm of the lever'25 carries the roller 11 on which the escapement rack 6 rests. When any one of the keys 12 is depressed, the corresponding key lever arm 16 raises the bar 17, and with it, the push rods or arms 18, thus causing the shaft 22 to be rocked. This movement of the shaft causes the [link 24 to be drawn down, and the lever 25 be rocked in such manner as to lift the roller 11 with the rack until the latter is free of the escapement pinion 5, and the carriage thus released to the action of the drum spring. In order that the movement of the carriage when thus released may not be too violent, there is provided a suitable braking device or governor, inclosedin a casihg 27, for checking the throw of the-car riage. The governor' aets on, the spring drum through a ,bev'el gear 28 on the governor' and a bevel gear 29 on the spring drum 2. These gears are ordinaril out of mesh (see Fig. 2) so that normally't e drum is free of the governor. The governor is mounted on the rock. shaft 22, and the latter in moving to lift the rack to release the carriage, rocks the gear 28 into engagement the key 10 releasing the r e arms 16'is a with the car 29 on the drum (see Fig. 3), so that w en the ca'rria e is released, it is under the control of t e governor. The movement oftheikeys 12'is limited by the bar 45 at the front of the machine, and the movement of the carriage releasing and governing mechanisms may also be limited by the engagement of the escapement rack with the carriage frame above the same as shown in' Fig. 3, or by other suitable stops. A coil spring 30 on the rock shaft by engage- T ment at one end with one of the brackets.

22"; and at the other end with the sleeve 21, returns the rock shaft and all connected parts to normal position when the key is released. The weight of the rackreturns it to the escapement pinion, and assists in the return of the other parts. The key itself is returned by the coil spring 30, acting through the bar17; and the keys on strikmg the frame bar. 60 at the front of the machine finally determine the return movement of the other parts.

As heretofore stated, there is combined in the'present invention a column selecting -mechanism, and a decimal tabulating mechanism. These mechanisms comprise a number of column stops suitably secured to the carriage and adapted to be adjusted thereon to'predetermined positions, and a set of movable key controlled counter stops which,

when actuated, cooperate with the column stops 'to' arrest the carriage in the desired positions. The movable stops whether used for column selecting, or for decimal tabulating purposes, are controlled from a single set-of keys 12 of which there are five shown in the drawings, but which may be of any desired number. These keys are preferably located at the front of the keyboard, as shown in Fig. 1, and are numbered I to V respect vely, key 'I representing the first column position, key II representing the second 'column position, etc. Each of the keys I to V.."controls a correspondingly numbered. row or bank of counter stops'32, preferably in the form of vertically disposed sliding rods, 'each counter stop having independent vertical movement in a casing 33 secured to the main frame of the machine. In Fig. 1 these counter stops are shown with their upper ends flush with the top 33 of the casing 33 when in normal or depressed position. The rows I to. V of counter stops are shown as parallel to the line of feed of the carriage. The

, rearmost row I of stops 32 is controlled by the I key; the next row by II key; 'etc., the front row fV being controlled by pin holes extend parallel to the direction of therefore, to' which of the keys 12 operpins 36, :which are suitably positioned in the riage. The column stops 36 project below the plate 34; and the upward movement of alin'ed stops is operated. The right-hand rows, numbered I to V, of perfora-r tions or pin holes 35, spaced ten to'the inch, or otherwise, according to the pitch of thef letter feed movement of the carriage. Each: row of holes is in effect a rack. The rows of{ movement of the carriage," and each row 01' rack is alined with one of the rows of stops 323- If more than. five keys 12 are employed, there will be a corresponding increase in the number of racksor of rows of pin holes. The plate 34 being-secured to the carriage moves? back and forth as a unit with the latter. i There areshown a number of plugs or stop perforations of the plate 34, in accordance with the desired column positions of the car- 'the stops y32 ,""when'the latter are actuated, is-snflicient to cause the elevated stop to intercept the path of any plug 36 which row is, brought by the movement of the same-and-arrests the carriage. .Each of the stops32 thusiorms a counter stop for the column stop 36 inthe corresponding row in the plate-'34. v V

The carriage when released continues its movement until some oneof the plugs 36 strikes anfelevated stop "32. According,

ated, .the movement of the carriage after release of the samemay be from one column to the next column, ormay involve the skipping of one or'more of the succeeding columns, before the carriage is againarrested; Obviously any one-of the five stops 32 in arow, whenoperated, will cooperate with any plug or which maybe n the corresponding row of perforations, and the stopping position 'of the carriage in a given column will depend upon which of the five stop of a row will arrest the carria sooner than will a-stop farther to the le in the same row. The spacing of the stops in each row is equal to the pitch of the letter feed movement of the carriage; so that, assuming the first stop to the right in a row to be the stop for arresting the carriage at the thousands position of a cohlmn, the next stop of the same row will arrest the carrings at the hundreds position; the next at the tens ;.the next 'at the units and the last one' to the left, at the decimal point position. The first stop to the right may of course be used as the decimal point stop, and those to the left as the tenths, hundredths, etc. The column steps 36 are usually-so positioned as to coopmte with the left'handcounter stop for any particular column is actuated by that key 12 which represents the selected column.

It has been stated that each of the keys 12 is adapted to operatethe counter stops of some one row. The means by which the keys control the counter stops, and are adjustable to select any counter'stop of the row controlled thereby are as follows: The rear arm 16 of the key lever of key V (see Fig. 4) terminates-under the forward or offset, so that, with the key V in the position shown 1n Fig. 4, the end of the key lever is under the left end stop 32 ofpoint stop of that row. Lever arm 16 of key lever 'IV is bent or ofl'set more than arm 16 of lever V, so as to be extended beyond the same, and hasa lateral extension 37 to bring the end of this. lever under the stops of row V of the stops. The lever arms of "keys III, II and I are progressively offset and extended, and have progressively longer lateral extensions 37, so that when all of the keys are in Fig. 4 position the ends of the key levers are alined of the resp'cctiverows of plungeis. At the end of each of the lateral, extensions 37 is an upward projecting tooth 38 for cooperat1on with the feet .of the counter stops 32. These feet are preferably provided with toengage not only the left end sto s of the respective rows, butany stop of t at row,

14 and 15 in such manner as to be capable not only of vertical but also of lateral swing. This universal mounting of the key levers is shown in Fig. 5. Each lever 13 is shown fitted within a slot 41in a spool 42, and mounted on a horizontal pivot pin 43 car-- ried by the spool, so as to have movement in a vertical plane, the slots being sufliciently long to permit of this movement. Each spool is held at top and bottom by set screws 44 which project through the cross pieces 1t and 15, and have pointed ends fitted within corresponding recesses in the top and bottom ofeach key lever." The tips of the screws serve as cone hearings on which the spools are adapted to turn, so that the key levers may be swung to right andlcft, and their ends therefore brought under any'selected stolp1 of the corresponding row of stops.

the frame plate 45 at the front of the machine, and under each key, is a comb 46, between the teeth 47' of which are slotsor counter stopBQ: to arrest the carriage at. the decimal point-position whenthe left hand spaces 48,o f suflicient width to receive the I key levers. The keys We normally held ele- V-shaped recesses. 40, and the teeth 38 are the keylevers are mounted in the cross pieces V row of stops 32, and isslightly bent 8. row V, this being ordinarily the decimal under the left end or decimal point stops In order that the key levers may be made key levers are out of theslots 48 (see Fig.

1), andvwhen in such position the key levers.

lie in the space between the teeth ofthe comb and the bar 60. Springs 49 secured to the cross piece 14 by meansof the upper screws 44, bear agrinst the sides of the key levers, and in so doin act to throw the keys to the right until t is'movem'ent is arrested by the shoulders 50 of the plate 45, in which position'each key lever is over the right end slot-48 of its comb, with its tooth 38 at its other end under the left end or decimal point stop. De ression of a key when in such position, e ects the operation of the corresponding decimal stop, which will be considered as the decimal point stop. If it be desired to operate the stop immediately to the right of the decimal point stop, the key is moved to the left against the action of its spring 49, until the key lever lies over the next slot-48, this movement causing the tooth 38 at the other end of thelever to move to the right until it lies under the next adjacent stop; whereupon the key lever is depressed into the slot 48 below the same, and the tooth elevated to raise the" stop. There is a slot 48 for each stop 32, and these slots serve to determine accurately the position ofthe tooth 38 with respect to the stop feet. The slots are shown as marked to in dicate the decimal, position represented thereby. The teeth 47 of, the comb are pointed, as shown in Fig. 1, so that the key levers may be readily guided into the properslots. No matter into what slot 48 the lever may be pressed, orwha-t stop it may have operated, whenever rcleasedit will first be thrown up to be disengaged from the comb, and will then be thrown to its normal right hand position by its spring 49. v

Secured at one end to hooks 51 on the stops 32 and at the other end to cross pieces 53 on the tabulator frame are coil springs 52 which serve to return the stops 32 to normal position when the keys are released. The springs 52 andcross pieces 53 are arranged-in tiers so that space enough for the springs may be provided. The arrangement of springs is as shown in Fig. 1. The five springs at the front take care of the five stops of row V. Row I is taken care of by five similarly arranged springs at the rear of the casing. The threeright end stops of rows II, III and IV are connected to the lower three'sprin right hand side of the casing; an the left end stops of rows II, III, and IV are connected to three springs in a; lower tier on the left hand side of the casing. This leaves the three central stops of rows II, III and IV, or nine in all; five of 'which are reached .Ifrom the five upper springs on the right hand side by means of hooks whieh pass inobetween the xows'pf,

on thestops 32; and the four remaining stops 32 are reached from a similar upper row of four, springs by means of hooks which pass in between the rows of stops from the left hand side. The springs 52 assist the spring 30 in the return of the key levers to normal position. Stops 55 in the form of studs which extend through the casing 33 from right to left serve to determine the normal position of the stops 32, and may also limit the u ward throw of the same. The opposing aces of rows V? and IV of the stops 32, and of rows III and II are cut or recessed at 56 to form elongated pockets through which the stops 55 are passed. The stops 55 are ofsuch size that the shoulders 57 formed by the recesses in the opposing stops32may all strike the stops 55, to arrest the movement of the stops 32 at the appropriate time. Two stops 55 th'erefore take care of four of the rows of stops 32. Another stop 55 serves the first row in the same manner. i

The followingis a rsumof the operation of, the machine: The columnstops 36 are first set in the plate 34 in the positions "which have been selected for the columns,

and therarriage' being thrown to starting position,,the machine is ready forwriting. "If there is writing to be done in the first column,' the first key 12 to be operated is key I. If the left hand stop 32 (ordinarily the decimal point stop) represents the desired stopping position in the first column, then key I is simply depressed; otherwise it is first swung to the left until over that particular comb slot 48 which rep resents the desireddecimal stopping position, the tooth 38 on the end of the'key lever beingthus brought under the selected decimal stop. The key'now being depressed,

releases the carriage from the escapement mechanism, throws in the governor, and simultaneously elevates the selected stop 32 of the rear row I of stops alined with that column stop 36 which is set in the rear row of holes 35. The'carriage when released moves with the plate 34 until thecolumn stop 36 ofrow I strikes the elevated stop, whereupon the carriage is arrested. On release of the key, the escapement rack falls back into engagement with the escapement pinion; the spring 30 throws outthe governor and acts through the bar 17 to return the key 12 to elevated position; the, spring 52 throws down the reviously elevated stop 32; and, as soon as t e key has been lifted out of its comb, its spring. .49. throws it tothe-right against its stop shoulder 50. The type keys are then oper ated for the writing of column I and, the writing in column I being finished,

' the column key for the next desired column j is operated. Obviously the carriage will .not

some one stop 32 in the corresponding row of stops is elevated. Consequently the carriage when once released will not stop until reaching the column controlled by whichever of the keys12 may be depressed. All columns cont-rolled by keys ahead of the depressed key will be skipped by the car- 15 may all beset in some one of the several -run from one colum rows of plug holes, no matter which, and only the key 12 which controls the corresponlding row of steps 32 need then be operated. When the machine is used in this manner, the same key will be depressed to release the carriage after each column is written; and, since the plugs are now all alined, the carriage will always be arrested at the next column'by the first on-coming plug 36. The decimal stopping position in each column will be determined in each instance, as heretofore described, by the adjusted position of the key over the slots 48 before the key is depressed.

The structure described is susceptible of considerable modification within the scope of the invention.
